timing the entry is the easy part nihilism........plenty here at H/C can do it..
it's the exit that is the really hard part.....
good folk feel the pain of,say a $500 loss...so they look to get it it back and don't use a stop loss.....
yet a gain of $500 doesn't create the same level of feeling as a loss does...so they are ambivalent about selling for a small profit.....ie,they don't let their profits run.
No amount of charting can solve that pyschological problem....and that's why very few can trade successfully.
